Why Diamonds.co.nz?


We have been diamond merchants in New Zealand since 1984 and selling diamonds online for over 10 years. Even though we use ‘up to the minute’ technology, we are not IT specialists, we are diamond and jewellery experts.

Lower Mark-ups

We pass the savings on to our customers with our unique business model. Even though diamonds are products of the earth, you shouldn’t have to pay the earth to own a high-quality diamond. You can be confident in the fact that we will not and can not have sales - our prices are true value all year round due to our low mark-up structure. Our model of no retail presence and low inventory costs enables us to be extremely competitive.
